Project Completion Time = 22 Days
Number of Critical Path(s) = 1

(A) As seen from the network diagram the scheduled completion of the project is 22 days.
(B) The critical path is indicated on the network diagram with red color and shown in the able table with as "Yes" in Table under "On Critical Path" column. The critical path is
B - D - F - G - I
The length of critical path is 22 days.
(C) As seen in table, EST for activity D is 4 Days from start.
(D) As seen in table, LST for activity G is 9 Days from start.
(E) As seen in table, EF for ...

Solution Summary

Answer four activity in box (AIB) problems on network construction, one comprehensive problem on network construction and one problem on scheduling and probability. This could be used as a good practice for project management.
